I also saw a set 325 Hoosier on 19'' forgeline with stock camber over the weekend at LCMT DE event. I'm running 305 and 265 trofeo's on 19'' Stark wheels with custom camber.

Car looks great and the 305's look incredible.

Can you say what size wheel width and the ET and/or spacers. Love to hear how those fit. Any rubbing? How was the balance of the car (understeer vs. oversteer)?

No spacers no rubbing the car felt neutral with tons of grip just point and shoot.

Man, that is a LOT of rubber to squeeze in the back. Maybe these guys know of some tricks that we are not aware of around here, or maybe they are just okay with rubbing

BTW, adding camber in the rear actually makes rubbing more and not less likely. When you shim the rear it pushes both the bottom and the top of the wheels outside and rearwards. And since you already have limited clearance on the outside it does not help.

I have been told by a race shop that apparently the 305 Trofeo R is about the same width as the 295 Cup 2's, so I can see them working, but dang, 325 Hoosiers? I'd like to know the details of how they got that done without rubbing...

That looks like you'll be rubbing all over

In taking a closer look at your setup, the Starke rear wheels have an ET of 67mm. I thought the ET of the OE GT4 rear wheel is 50 (anybody correct me please). A 17mm difference would mean the inside of the wheel would by that much closer to the suspension, but obviously it seems to work. Seems like a really tight fit.

I'd seriously do more research on the Chinese/Taiwanese "Starke" brand before using them for track purposes.

The rears are 42mm, pushing them out.

I'm confused as well. Get PTS, Trofeos and then some odd brand wheels.

Wouldn't a 67mm positive offset be pushed further inward than a 42mm offset?

There is more to the story I'm guessing if these are 19" wheels. If there was a way to make the toe-arm lower profile to clear the barrel of the wheel, there is more room in the wheel well to be had.

Yes I did my research and satisfied myself with what I found They are VIA and JWL stamped.
The race shop i'm dealing with are fine with them. They are a low pressure cast wheel same has the OZ Leggera.

Would've loved to have some Forgeline but for I couldn't stomach the 7000$ CAN for them now on top of all the other items I've put in the Car ( Roll Cage, Harness, all the alignment components, Braided brake line, caliper stud kit, wheel stud kit....plus the man hours, believe me the numbers do add up very quickly.

They do fit and I believe they'll do the Job If they dont Well I'll report to the forum and would have taken one for the team.

I think if a few people actually try these brands like Stark so we have some info on them, that would be helpful. I've been to plenty of factories in Taiwan and their facility and quality is quite high. You just have to find the right manufacture as there are plenty of them doing work for Rays and other brands. Its all about quality control.
